What is causing my cat to attack people?

Answer by  Tracipoo (1329)

It could be that someone is secretly being mean to your cat. My boyfriend was secretly being mean to her dog and he started biting people. He had never done that before and it was because he thought he always had to defend himself.

There is a possibility that during the first few weeks of his life he didn't receive much human contact and if that is the case, there is a good chance he will never change this behavior. If your cat is older it may be because it is paranoid, something that commonly happens to older cats.

Your Cat could be sick. Sometimes when cats are sick they get very territorial and they start to act in ways they never have before. I suggest you take your cat to the vet to make sure everything is fine.

The first thing that comes to mind is hormones. If your cat has not yet been spayed or neutered, hormonal changes can definitely cause behavioral changes. Also, if your cat is not feeling well (sick or possibly injured) it can result in aggressive behavior. Environmental changes and stress will also cause a cat to behave differently.

This sounds like it is a result of a new stress in her life; have you changed things lately? Have you began or stepped up a new relationship? Your cat is feeling insecure and scared, so you need to figure out how to make her calm down and respond well to people.
